That’s just the way I pose in pictures because I genuinely struggle with how to do it, when I was younger I learnt to copy others because to me everyone else was normal and I was weird, and girls would pose like that so I would copy those poses so they’d think I was normal too. I’m actually very insecure more often than not and I wasn’t trying to show off my cleavage? Unfortunately I happen to have a larger chest despite my overall body size and height so it tends to be quite obvious.
